Embodiment Construction
[0032] The intelligent protective dry-type air-core reactor of the present invention uses different sensors to collect real-time voltage and current change signals and temperature change trends of the dry-type air-core reactor, and at the same time obtains the working power of the sensor by means of electromagnetic induction; the collected real-time signal Through the signal collection device 21, it is transmitted to the protection control device 31 for monitoring and processing. When the set parameter critical value is reached, the protection control device 31 sends corresponding control signals to the vacuum circuit breaker 41 and the fan 42 to complete the dry-type air-core reactor. heat dissipation and relay protection.
[0033] Such as figure 1 As shown, the intelligent protective dry-type air-core reactor of the present invention includes a dry-type air-core reactor 01, a temperature sensor 11, a voltage transformer 12, a current transformer 13, a signal acquisition devi...
